  • Methods of preparing carbinized nanotube composite and metal-nanotube composite catalyst
    Patent number: 8648004
    Abstract: A method for preparing a metal-nanotube composite catalyst for an electro-chemical oxygen reduction reaction includes: debundling carbon nanotubes (CNTs); loading a carbon-containing polymeric material onto the surfaces of the nanotubes that have been debundled; carbonizing in situ the carbon-containing polymeric material on the carbon nanotubes to form carbon char layers surrounding the surfaces of the carbon nanotubes; and loading metal catalyst particles on the carbon nanotubes. The carbon char layers contain high amount of nitrogen and may be formed into a porous structure.
    Type: Grant
